Liev Schreiber and his son Samuel hopped on a bike for a ride around NYC yesterday. The adorable duo smiled big as they peddled through the streets of TriBeCa together. Mom Naomi Watts skipped the two-wheeled transportation and was spotted talking on her phone while walking around SoHo solo. She was dressed for Fall in plum colored pants and a bright purple scarf after getting glamorous at an event earlier this week. Naomi attended "An Evening With Ralph Lauren," which was hosted by Oprah Winfrey at the Lincoln Center and benefited the Ralph Lauren Center for Cancer Care and Prevention. The star-studded night also brought out Jessica Alba and Cash Warren, Kerry Washington, and Jerry and Jessica Seinfeld.
